The caps'j are both provided with the Words On and Oil as sl at it and on the opposite sides of which are placed arrows in and k which indicate, re spectively', the direction in which said caps are to be turned to throw the clutch mechanismont of'operation or into operation, and the sleeves d are provided with stop pins in and the caps j with lingers 7: which operate in connection with said stop pins and which limitthe movement of the caps j in one direction, and said sleeves may also heprovided with marks to indicate the proper limit of the movement of said caps in the op posite direction.

-The threads between the caps j and the sleeves d are left threads audit will be an derstood that, with the parts in the position shown in Fig. 2, when the caps j are turned to the left the Washers 2' are forced inwardly and the sleeves (Z are drawn outwardly against the operation of the springs and when said caps are turned to the left, the Washers 2" are relieved ot'pressure and the springs It force the sleeves d 'in'vvardly.

It will be understood that the screw, I may be screwed'into the Shaft 61 or out of it so asv to regulate the tension ht the spring 5*, and the screw i the washer 2". and the spring 2" serve to take up all the loose action and to prevent the mechanism from rattling when in use, and an operator when accustomed to the manipul Y may determine by the cap striking the Washer -a'.when turned in one direction how :tari said cap should be turned in order to operate the "parts as hereinbefore described.

From the foregoing description it will be seen that the clutch teeth ai and c are intended to hold the operative member at one end of the shaftflstationary, while-the operative member; at; the other end of the shaft is-in use, when it is, desired to use only one of said operative members but these clutch teeth are not an absolute essential feature of my inventionaiid may or. may not he employed. It will also be under-steed that the mechanism at both-ends of the shaft 1 is town in Fig. l

I and for this rea the mechanism connected with on said shaft is shown in'section.

Myimproved, clutch mechanism is Well adapted for the object for which it is in- 7 tended, and changes in and modifications 0t thej'constrnction herein described may be made, within the scope of theappended claims, Without departing from tlie'spirit of my invention or sacrificing its advantages.

Having fullydesc'rihed my invention, what I'C ldlln new and desire to secure by Letters Patent,"is:

1.. A clutch mecha motor shaft, said m main stationary sleev screwed onto the end nism for the ends of a echanism consisting of o es, supplemental sleeves s of the'shaft and provided with set screw keys, said supplemental sleeves being provided at their outer ends with outwardlydirected flanges having in- 5 Wardly directed clutch teeth, sliding sleeves mounted on=-said first-named sleeves'and movable longitudinally thereon and pro-' vided between said sleeves with inwardly directed annular ribs having on their inner sides clutch teeth adapted to engage clutch devices on the outer ends of'the main sleeves, said sliding sleeves being also provided on their outer ends with clutch teeth adapted to engage the teeth on the flanges of the supplemeutal sleeves, and said sliding sleeves being also provided with apertures through which the set screwkeys of the supplemental sleeves are passed and a cap screwed onto the outer ends of the sliding sleeves and inclosing the end of the shaft and the supplemental sleeve l A clutch mechanism for the ends of a oznprising main stationarysleeves. supplemental sleeves screwed onto the ends ofsaid shaft, sliding sleeves mounted d'supplemental sleeves. said main and sliding sleeves being provided with clutch devices and said sliding and supple mental slee devices means for keying the supplemental sleeves tothe shaft; and adapted to be op erated through the sliding sleeves; spiralsprings operating on the slidingsleeves-and the inner ends of the supplemental -sleeves, 1'15 screws. inserted into. theends of the shaft, spiral springs and washers mounted on said screws, and ca 5 screwedonto the sliding sleeves a'nd inc osing the ends of the shaft" and thesupplemental sleeves'iind adapted 1.21 to operate in connection with the-Washers o the screws. H v p I 8. In a clutch mechanism for'power-shafts, a statimmry sleeve, a'snpplementalsleeve screwed onto theend of the shaft; a sliding 125 sleeve mounted on the adj'eeent end portions of the main supplementalsl'evo, said sliding sleeve and sai I heing'providtf with interoperative clutch. de lCGSyfiiIlds-Sflida supplemental sleeve and seid."s1idi11g' sleeve {1 30 ves being provided with clutch beingprovided with inter-operative clutch devices, said supplemental sleeve being also provided with a set screw which is passed through an aperture inflthelsliding sleeve, a

of the main supplemental sleeve, said sliding sleeve and said main sleeve being provided with inter-operative clutch devices, and said supplemental sleeve and said sliding sleeve being provided with inter-opera ativo clutch devices, said supplemental sleeve being also provided with a set screw which is passed through an aperture in the sliding sleeve, a spiral spring'placed at the shaft and the supplemental inner end of the supplemental sleeve and operating to force the sliding sleeve inwardly, and a cap screwed onto the sliding sleeve and inclosing the end of the shaft and the supplemental sleeve, said end of the shaft being'also provided with a screw on which is mounted a spiral spring and a washer in connection with which said cap operates. 5. The combination with; the end of a power shaft of a clutch sleeve movable longitudinally thereon, a cap screwed onto said sleeve, and means whereby the turning of said cap in'one direction will lock said sleeve to said shaft, and in the opposite direction will release said sleeve.
